Does Calcium Hypochlorite raise CYA??

I just drained my pool a little in an attempt to lower my CYA. Does Calcium Hypochlorite raise CYA ??? I have 2 packs left of the Robarb Pool Specialties "Power Blast". Ingredients state Calcium Hypochlorite 68%, other ingredients 32%.

Re: Does Calcium Hypochlorite raise CYA??

No. But it will raise the CH. Since you have a vinyl pool, the CH wouldnt be a problem unless it got exhorbitantly high, at which point you stand the risk of calcium precipitation.
